Title: Improvements relating to hydraulic control mechanism for variable-speed power transmission mechanism
Filed: 1931-08-19
Abstract: 392,587. Controlling variable-speed gearing. HAYES, F. A., Middletown Township, New Jersey, U.S.A. Aug. 19, 1931, No. 19030/32. Divided on 392,570. [Class 80 (ii).] Controlling-means for variable-speed gearing suitable for vehicles comprises a ratio-controlling fluid pressure actuated piston 70 which moves in a cylinder 71 until it reaches a definite position with a certain speed ratio in the variable gearing, not shown, whereupon an outlet 71m is uncovered through which the operating fluid is allowed to leak away subject to regulation by an operator-actuated valve 71i, which may be associated with the control means 74a of the engine throttle 75a. In the arrangement shown, oil from an engine-driven pump enters the cylinder 71 by way of a pipe 71a and acts on the control piston 70 against a spring 72 and against the speed gear reaction. In a low-speed position shown, a port 70a in the skirt of the piston 70 registers with an outlet 71b in the cylinder wall and thereby permits oil to leak idly past a set control valve 71d until the engine is accelerated. The piston then moves, closing the outlet 71b and raising the gear ratio until another port 71r in the piston skirt arrives in register with the outlet 71m in the cylinder leading to a pipe 71n leading to a port 71p into a second cylinder 71g. The sleeve valve 71i in the cylinder 71g is connected by a rod 75b to the accelerator pedal 74a, which operates the engine throttle 75a. In the valve sleeve 71i is a port 71k which at a certain accelerator pedal depression registers with the port 71p then allowing pressure oil in the pipe 71n to pass freely to the sump by a drain 71h. The parts may be set to allow this escape of oil through the drain 71h at any desired degree of throttling of the engine at 75a. The action of this control device is described in Specification 392,586.

Title: Improvements relating to the control of point operating mechanism
IPC: B61L21/06
Filed: 1928-06-30
Abstract: 299,417. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Loomis, H. S.). Oct. 26, 1927, [Convention date]. Electric control.-Railway points-motors, controlled by a hand lever, have control means which renders the lever ineffective and causes the points, if in an intermediate position, to move to their extreme position when a train approaches the points. The track section 1, 1<a> in front of the points 3 is included in a track circuit which contains a relay G normally energized as shown. When a train enters section 1, 1<a> relay G is deenergized and the arms 18, 30 engage the back contacts. The points are directly coupled to circuit controllers C and E, the former connected to asymmetric units 21, 25, 26, 36. To move the points to reverse, lever D engages arms 15, 16 with contacts 15b, 16<b> to complete a circuit from the lower terminal of battery 12 through leads 13, 14, contact 15b, arm 15, lead 17, arm 18, lead 50, reverse magnet R, lead 20, unit 21 and lead 22 back to the centre of the battery. Current also passes through lead 23, winding 8 of lock magnet L, contact 9<a> and unit 25 to lead 22. When the points reach their reverse position, contact arm 9 engages contact 9<b> to de-energize magnet L, and arm 10 engages contact 10<b> to complete a circuit through lead 22, unit 26, arms 10, 16, and cabin lamp 32 to include the upper part of the battery 12. If a train reaches the track circuit before the points have been moved, the lock and reverse magnet circuits are broken and no movement takes place. If the points have moved but have not reached their mid-position, they are returned by the circuits (1) lead 43, arms 11, 30, leads 52, 53, normal magnet N, lead 35, nuit 36 and lead 22, and (2) leads 52, 37, winding 7 of lock magnet L, lead 38, contact 9<b>, unit 25 and lead 22. If the points have passed their midposition, they are moved right over by the circuit, lead 43 and arms 11, 18 to reverse and lock magnets R, L as for reverse operation. Similar action takes place if the points are being moved from reverse to normal position, lamp 40 being included in the circuit to indicate normal position of the points. Specification 220,929 is referred to.

Abstract: 823,588. Packaging-machines. DEHN, S. G. (Compressed Products Corporation.) June 17, 1957, No. 19062/57. Class 94(1). [Also in Group XXX] A machine for packing articles such as sanitary napkins into tubes comprises means feeding tubes to a turret, the turret carrying the tubes past means to insert and compress a napkin within the tube, means to close the tube ends and means to eject the finished package. Open-ended tubes 51 are fed down a shoot 53, Figs. 1, 2, by opposed belts 54, 55 towards the turret 22, the drive being continuous and frictional. The turret carries a series of tube holders 26 having clamping jaws 27, 28. The jaws 28 are biassed to tube clamping position but are retained retracted during tube entry and package ejection by a cam 64, Figs. 1, 4. The entering tube is positioned by a fixed bracket 63 and is transported by the turret to a filling station. The napkins are fed by a conveyer 70, Fig. 9, into the path of reciprocating pushers, 88, 89 (see also Figs. 1, 2) which free them from conveyer clips 72 and pass each one into a compressing chamber 91 at the filling station. The chamber is formed by fixed members 107, 108, 111, and a reciprocating member 112, Figs. 1, 2, 9, 10, which last compresses the napkin to circular section on its inward stroke. On either side of the tube at the filling station and the compressed napkin, which is aligned with the tube, are reciprocating rods 132, 140. These rods are aligned with the napkin and tube and with openings in the members 129, 130, Figs. 1, 2 and 10, in front of which pass intermittently moveable tapes 123, 124, Fig. 1. As the rod 140 advances towards the napkin it punches out an end disc 147 from the tape and forces it with the napkin into the tube. The rod 132 cuts a similar disc 139 and carries it into the tube, the napkin being compressed between the rods. The turrett carries the packed tube to an end securing station where spinning heads 172 in shields 174, Figs. 1, 14, turn in the tube ends upon the discs. Finally, the completed package is ejected by a reciprocating rod 209, Fig. 2, the clamping jaws having been opened by the cam 64 adjacent the ejecting station. A handwheel 221 enables the machine to be turned over by hand for adjustments &c.

Abstract: 745,799. Face conveyers. STAMICARBON N.V. June 30, 1954 [July 2, 1953], No. 19210/54. Class 78 (1). In a face conveyer provided with a trough formed by a plurality of sections which are capable of a certain articulation one with respect to the other, and carrying on one of its walls a sectional guide rail for a reciprocatable mining-machine, between each guide rail section 8 and the adjacent wall 2 of the conveyer section there is provided a guide-plate section 11 adapted to provide a vertical guide face for the machine. The angle forming between adjacent rail sections 8 when the conveyer sections articulate is reduced by making the sections 8, 11 shorter than the conveyer sections and providing short plate and guide rail sections 15, 20 which bridge over the ends of adjacent conveyer sections, these sections being held in place so that the adjoining conveyer sections may articulate in the vertical and horizontal planes relative thereto. The sections 8, 11 are secured to the trough by bolts 7 which engage in blocks 5 secured by bolts 6 between pairs of plate members 4 provided in a channel 3 in the wall 2. The sections 11 are properly located by studs 9 protruding from the back of the sections 8 fitting in holes 10 in the sections 11, the heads of the bolts 7 passing into the recesses 13 of the studs so as to be kept clear from the channel 14 of the guide rail which may serve as a guideway for the hauling means of the machine. Braces 12 on the section 11 fitting in the channel 3 enable the section to be centred on its trough section. Each plate section 15 is of such a length that a gap 16 is left between each end of the section and the end of the adjacent section 12, and is provided with tongues 17 which engage in recesses 18 in the sections 11, a small clearance being allowed between the tongues and recesses so that the long and short plate sections are capable of a slight relative articulation in the vertical plane. In a modification (Fig. 9, not shown), the tongues are provided on the sections 11 and are each formed with a rounded end portion which engages in a recess in the section 15. Each rail section 20 is secured to its plate section 15 by welds 22 deposited around the edges of holes 21 formed in it. Specifications 719,674, 729,078, 729,079 and 729,374 are referred to.
